Intentionally or accidentally. Could be physical, interpersonal or conceptual/intangible.
Was working at a kitchen as a dish washer. Had this little cart to pick up plates etc. from the restaurant side. Was just returning the cart, fully loaded into the kitchen, to the dish spot and bumped the wheel into something, or it jammed. Tons of plates and food scraps on the floor…
Accidentally wrote a 2GB ‘nohup.out’ file when I forgot I had a script running as nohup in the background without redirecting STDOUT and STDERR to /dev/null.
Basically, I forgot to prevent saving the output of my program to a file, and it created a massive file because of it.
2GB might not seem like much, but this was on a server with ~5GB free space left. Could have been worse had I not caught it sooner.
I didn’t make it, but I let it happen to teach a stupid company a lesson.
Worked as a Change Manager for a manufacturing company. They built stuff destined for landfills and you probably have one of their appliances in your home.
To set the stage, my job prior to this was as a Problem Manager/ Major Incident Manager for a large insurance company. On major incident I worked was the when a Pure Storage technician came in to replace a failed drive. A bug in the Storage O/S allowed an active drive to be shown as deactivated and safe for replacement. This did not happen all the time, only during a certain set of circumstances. I don’t remember the details of that though.
My fellow IT professionals know full well what that means. That array supported a Tier 1 app and the whole thing went down hard. Not just hard, but it corrupted the database that required a multi-hour restore to fix. I also ran the Problem record on that one and knew everything about the who, what, and why of that outage.
Fast forward a year and I accepted the contract to be the Change Manager for this manufacturer. In comes a change request to replace a failed drive in a Pure Storage Array, except this time instead of paying for a service contract, this company cheaped out and did all the service in house. Which I didn’t know Pure Storage allowed you to do, this was 6 years ago, but this company somehow managed it. The storage guy was a bit of prick and hated the whole Change process. Which I get to be honest, but if you want to play in an enterprise environment you need to follow procedures. So he submitted his change with little to no detail and only one director on the CAB had any familiarity with storage systems. So I started asking technical questions, which generally is inappropriate of a Change Manager as that’s not the job. When I asked what the O/S version was, I got heavy push back that it wasn’t relevant. When I attempted to state WHY I was asking, I was told the change was approved and to move on. As replacing a failed drive in such a large array is generally regarded as low risk. My boss actually reprimanded me for taking so much time and extending CAB longer than it should have been.
I asked her (my boss) who was on call for Major Incidents the time of the change and… It was HER. LOL
So if you’ve guessed that the Storage team of this company were idiots and the O/S version their Pure Storage Array was running on still had the bug, you are a winner winner chicken dinner. They also had the fantastic luck to run into the circumstances as well.
Cue another Major Incident that my boss had to manage. It took over a day to resolve and all the while several production lines were sitting silent. Hundreds of thousands of dollars of loss in production. If not millions.
When someone with almost 30 years (at that time, I’m over 30 years now) tells you that something can happen, because they’ve seen it before… FUCKING LISTEN TO THEM.
I didn’t have anything to do with the Problem Process at that company, but I did sit in on it and you’re damn straight if I didn’t deliver the biggest I fucking told you so in the history of that company. The company also bought a support contract from Pure, I made sure that was a task on the Problem Record.
As to the biggest mess I made personally… I was 2 or 3 and had the bright idea of smothering myself in an entire jar of peanut butter. My oldest brother was baby sitting me at the time and our mother made him clean me up. Apparently the smell of peanut butter and water was so bad that my brother, even 53 years later, cannot stand peanut butter at all.
I flooded a dormitory once, but I blame building maintenance for tricking me into it.
I wake up and head to the bathroom. Turn on the shower, nothing happens. Try the sink, still no water. No advance notice to the residents, but the water must have been shut off for some reason. I have a class to go to, so I turn everything “off”, get dressed, and leave. I’d forgotten that one of the sink knobs was threaded the opposite way from the standard convention, so that one was full on when the water was restored. Came back to the dorm after lunch and realized exactly what I’d done as soon as I entered the hallway and saw the maintenance man running his shop-vac outside my room. It overflowed the sink drain, and the bathroom floor drain, flowed through the dorm room, and was in the process of flooding the hallway.
Maintenance’s fault. Good answer
I was trying to move a job site, well seasoned porta-potty with a Bobcat. I should have strapped it to the forks……….
Both involving One of these
First time my manager was micromanaging me what buttons to press, so I did a malicious compliance and let him make me spill around 150kg of honey on the floor.
Second time I tried teaching a new lad how to work it, and he insisted that I shut up and leave him to it because he knows how to do it because hes not thick and it was pretty insulting that I thought he was that thick. Just stood back and casually watched him spill 2 tons of beef and blood all over the floor.
Neither one was properly my fault, but I deliberately did nothing to stop either one and laughed inside the whole way.

Is that a mixing drum? Where were you making with honey and beef?
The honey was for honey-roasted ham, and the beef was just frozen beef that got defrosted. Separate instances like.
Gotcha, thanks! Now I’m hungry.
I love those answers
I married a bipolar woman. Those were 3 interesting years.
Yikes! I nearly married a gal with Borderline Personality Disorder. Absolutely insane. So glad my wife is normal.
That’s not an easy cross to bear
As a young child I got up early and decided that I would cut my own hair as a gift to my parents.
The big problem was the small mirror in the kitchen was too high so I was jumping, snip, jump, snip, etc.
When complete I went up to wake them to show them their “gift”.
I still remember the look on my mother’s face. I couldn’t understand why she was horrified hahaha.
Edit: I just remembered another little detail… She took me to the hairdresser’s as soon as possible and when the lady asked if I’d cut my own hair I was like “how did you know???” Lol
Thats fantastic
Thanks. It’s a good little mischief story :) Great thread!
We did Work Experience at my school and I managed to get a place at a local radio station. Now, what’s the worst thing a work experience kid could do at a radio station specifically? If you answered “take the entire station off the air” then you’d be right.
Could be worse, you didn’t trigger a visit from the FCC!
Hellllll yeah
I went to a private university 20 years ago
Ooooooof thats a rough one bud
I drained an entire airplane’s fuel tank onto the hangar floor once. Wasn’t really ready to mop up 26 gallons of avgas.
Jesus thats a pricy mistake
I don’t get why someone downvoted you. You asked for big messes and this is one and you commented as much. The internet can be weird.
Probably someone that just doesn’t like me based off other posts. I could not care less about a few downvotes if the thread is going well.
Oh yeah it doesn’t matter at all. It’s just fascinating to see how petty people can be.
I love that shit
Oh gosh, the smell, the white lead splotches!
It might be why I’m like this.
I need to set the scene first: Me, about 12-13 years ago, on the surface looking like a respectable career and family man, pillar of the community…Behind the scenes slowly falling apart, trapped in an abusive marriage, a job I hated more and more each day, and told that I had to keep the happy face on for the sake of everyone else.
And one day I just fucking imploded. Left for work one morning like normal, halfway there I threw my phone out the window and decided I was done. I remember driving and driving, stopping a few times for food or just to get out of the car and meander…but I had no real direction, started to panic about the possibility of going back to hell or staying lost out here. I blacked out.
Apparently my car ran out of gas and I ditched it. I was told when they (they being the cops) found me I was several states away, couldn’t remember my name, was talking nonsense, and was covered in my own filth. I was involuntarily committed and when my wife tried to visit me I tried to attack her, told her I wanted her dead, that she better never come near me again. That was the last I ever saw of her or our kids. My dad had no idea how to handle this so he just decided to treat me like I was dead and sold off most of what I owned, and at the time I was too inside out to care. I was in and out of psych wards for the better part of three years.
So yeah, destroyed a family, a home, my career and reputation, and caused a ruckus in a sleepy little rural shit town. I did get better…much better, and I’m happier and more together than I’ve ever been, but that’s the boring part of the story.
Well fucking congrats on the recovery from that. I’m sure it was very difficult. Glad to hear you’re doing well now.
oh my word, it sounds like you’ve been through hell and back. I’m glad you made it out!
This might sound weird, but now I look at that psychotic break as something that had to happen so I could get where I am today. I’m more lucid, my thoughts are less chaotic, and I have better agency to deal with people and situations that I know are bad for me.
that makes sense, and it got you out of a bad situation. I don’t know what else to say other than I’m happy for where you’ve gotten to and here’s a hug 🤗
factory I worked at, I snapped a bearing rod on an injection machine.
it was made of steel, about 16 inches in diameter, about 18ft long, and cost around $1.5 million to replace.
complete accident, required a mandatory one week off (no pay) while they investigated if it was due to negligence or just routine wear and tear.
it took them six months to get a new one and cost the company close to $100 million on lost revenue on top of the cost of the part.
Mandatory week off with no pay. Bummer. Pretty sure that’s illegal in my country.
probably is if you live somewhere with workers rights and a pro “human” government.
I live in one where corporations get more rights and support than the homeless.
Did you keep your job after that?
I did. I was a good employee, worked hard, and was well liked. it was also found that there was a flaw in the rod that caused it to fail.
Ah, so you were the poor bastard it broke on. Well, I’m glad they recognized you and didn’t reactionary fire you for it.
I accidentally set a model home on fire when I was 12 while trying to burn bugs with a magnifying glass. Not a toy model, but like the house they show buyers to get a sense of the layout of the house they would have built.
Sid Phillips, is that you?
I can’t remember exactly what happened, but my parents have a photo of me when I was little and my face very full of chocolate cream :)
